Claims. 1

This invention relates to utensils particularly of the egg beater typein which a supporting frame is clamped to the edge of a table, or thelike, and in particular this invention relates to a machine actuated bya hand crank for shredding the meat from halves or parts of coconuts.The purpose of this invention is to provide means for clamping part'of acoconut or the like while shredding elements are actuated with arotatable and at the same time advancing movement to shred the meattherefrom.

' In the usual method of shredding coconut in the Philippines a halfround blade with a saw tooth edge is attached to the end of a stickmounted on legs and the coconut is worked over the end of the bladewhereby the meat is shredded from the shell. By this means it isnecessary to hold the part of the coconut being shredded in the hand andit is not only difficult to hold the coconut in the shredding positionbut with this conventional method there is danger of injuring thehands.With this thought in mind this invention contemplates a coconut shredderin which part of the coconut is clamped in a frame with the meat exposedand shredding knives are actuated over the meat until the meat isremoved from the inner surface of the shell. The object of thisinvention is, therefore, to provide means for clamping part of a coconutin shredding position and also means for actuating shredding elementsover the inner surface of the part of the coconut. 7

Another object of the invention is to provide a coconut shredder inwhich uneven sections of coconuts may be shredded.

A further object of the invention is to provide a coconut shredder whichis of a comparatively simple and economical construction.

' With these and other objects and advantages in view the inventionembodies a substantially -U-shaipe frame having a 'supporting clamp onthe lower end with a horizontally disposed shaft, means for rotating theshaft, means clamping sections of coconut against the end of the shaft,and shredding elements actuated to shredding position by the shaft.

Other features and tion will appear from the following description takenin connection with the drawings wherein:

advantages of the inven- Figure 3 is an end elevational view of theshredder looking toward the handle thereof.

Figure 4 is a plan view of the shredder.

Figure 5 is a detail showing a section taken on lined-5 of Figure 1illustrating the mounting of the shredding elements.

Figure 6 is a detail showing a section taken on line 5-6 of Figure 1showing a section through the shredding knife. 7

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved coconut shredder of this inventionincludes a frame having a post [B with an upper arcuate section H, athreaded shaft 12, a coconut gripper I3, a clamp screw l4, shreddingknives i5 and i3 and a handle IT on a crank 18. The post If] of theframe is provided with a clampat the lower end having spaced flanges l9and 28 with a thumb screw 2! threaded through the flange 2B and thethumb screw is provided with a washer 22 and a lock nut 23. By thismeans the frame is clamped to the edge of a table as indicated by thenumeral 24, as shown in Figure l.

The shaft I2 is journaled in a bearing 35 in the post It and the innerend i provided with spaced fingers 26 that are forced through the meatof a coconut so that they engage the inner surface of the shell, asindicated by the numeral 21 whereby a half or portion of a coconut isforced against the fingers 26 on the end of the shaft. by the clampscrew l4 through which the prong 28 of the gripper I3 is rigidly clampedin operative positions. The gripper I3 is provided with a stub shaft 29that isjournaled ina socket 3G in the end of the screw 14 and a ball BIis positioned between the inner end of the stub shaft and base of thesocket. The stub shaft 2% is also provided with an annular groove 32into which the end of a screw'33 extends, as shown in Figure 1, toprevent accidental'separation of the gripper from the screw. The rearsurface of the gripper i3 is provided with radially disposed gear teeth34 and a beveled pinion 35 is positioned to mesh with the gear teethwhereby upon rotation of the gripper a feeding element 36 on the lowerend of a shaft 37 journaled in a bearing 38 in the lower end 39 of thearcuate section it of the frame is rotated. The feeder shaft 31 issuspended between springs to and H on opposite sides of the bearing 38with the spring it engaging the hub of the gear 35 and the spring llengaging a collar '42 on the shaft 31.

The shaft 12 is rotated by the handle 11 of the crank it through a jackshaft 43 that, is mounted end of the shaft l2 which forms a fly wheeland also provides means for sharpening knives, tools, and otherimplements.

The end 39 of the section H: of the'frarne is pivotally mounted by pins52 and. 53 the outer ends of which are threaded and provided with thumbnuts 54 and 55, respectively: With" theend 39 mounted in this manner thefeeder 36 with the shaft and gear may be swung upwardly toa positionabove the clamp screw 14 when the beateris not in use. A lock nut 55Witha handle-51 extended therefrom isprovided for securing the clamp screw Min the position of clamping part of a-cocoanut against the fingers 26 onthe end of the shaft l2.

The-shredding knives l5 and iii. are provided with serrated edges 58 and.59, respectively and the knife i5 is carried by an arm 60 that ispivotally mounted on a base 6! on which the knife l5-is mounted througha stationary arm 62'.

The. knives are eccentrically positioned with theknife l5 pivotallymounted by a pin 63 in a yoke 64 on the end of asleeve 65 and the sleeve65-is positioned over the end of the arm 59 and secured in position byaset screw 65. The yoke is urged' outwardly bya spring Win the. end ofthe socketfit-in thesleeve 65. The knife 25 is secured in operativeposition by a spring 59, one

7 end of which is attached to an eye 10 on the sleeve 65,- and the otherto the end of the knife l5 through'an opening. H. The arm 69 isprovidedwith spaced-side bars 12 and 13 and'the side bars are providedwith slots 74 and T5, respectively, that are positioned over studs 16and 17 on;;the sides of the-base 6i, and-the:side bars are securedinposition by thumb nuts It-and 19,,respectively.

Theshredding knife -I Son the upperend of the armitziispivotally mountedin a'yoke Bilby a pink)! and a sleeve 82 on theinner end-of the yoke is:adjustably'mounted-on the arm 62 by a set screw 33. The sleeve-daisprovided with-a spring 84 and a spring 85 holds the shredding knife inoperating position, one endbeingj attached to the knifeifi'through anopening: 86 'and the other to the sleeVe-SZthroughan eye-87.

The shaft i2 extends through .a mounting tube 88extended inwardlyfromthepost It and the sides of thetube areprovided with slots39 and 90'throughwhich projections 9i and 92 of the basefil extend as shown in Figure 5and with .the inner surfaces of the projections 9i and 92 meshing withthe threads of the shaft l2'the base BI is advanced toward the sectionof the coco nut when the screw isrotated by the crank.

With the partsarranged in this mannera h'alf orsection of a coconut ispositioned; as indicated by'the numeral Zlwith the'iingers 26'of theshaft I2 forced through the meat on the'inner surface of the shelland'with'the prongs 28 of the gripper l3'forcing the shell against thefingers 26; With the coconut secured'in' this'manner'the shredding knifel5 ispositionedto contactthe inner surface .of the meat of the'coconutand as -the'co'conut is rotated by the crank" lW-theshreddiiig 4 knife[5 is advanced by the threads of the shaft [2 whereby a shredding actionis obtained. As the operation continues the shredding knife I6 moves incontact with the meat of the coconut at the center and substantially allof the meat of the coconut or part thereof is shredded.

The positions of the parts are readily adjustable-tocorrespondwiththe-size and shape of the coconuttandwith. the parts-of the coconutreadily removed and replaced in this manner a comparatively largequantity of coconuts may be shredded in a relatively short period oftime.

Wherr'the device is not used for shredding coconuts,knives, tools orimplements may be sharp- 4 enedionatheagrinding surface of the fly wheeland the beater 35 maybe used for beating or mixing material;

Ittwill: be understood that modifications may be made in the design andarrangement of the parts .withoutdeparting, from the spirit of theinvention.
